Description

Road ice prevention system {PREVENTING ROAD-FREEZING SYSTEM}

The present invention relates to a freezing prevention system for preventing accidents caused by freezing by installing in the freezing section of the road.

Winter snowfall and freezing of roads caused by water can cause vehicle slipping accidents and are a major factor in winter traffic accidents.

Conventionally, sand spraying or calcium chloride spraying is used as a road freezing measure, and this method is repeated every year because other solutions are not suggested, even though it is not possible to fundamentally solve the sliding accidents on ice roads. Road maintenance costs are being consumed.

Table 1 and Table 2 show the results of the traffic accidents and the material input for re-establishment work during winter season (1998.12-1999.1.23) in Deokjin-gu, Jeonju-si, Jeollabuk-do. It is very large and consumes huge manpower and cost, but its effect is weak, indicating that it is not possible to fundamentally solve the occurrence of traffic accidents caused by road ice.

Even though huge costs and manpower are consumed each year for snow removal, traffic accidents caused by freezing cannot be prevented fundamentally, and the number of casualties due to freezing is not reduced every year, and the resulting socioeconomic losses are very high nationwide. It is urgently required to propose a way to fundamentally prevent road freezing due to the enormous situation.

The present invention has been made for the purpose of effectively preventing the winter traffic accidents that are repeated every year by providing a new means that can fundamentally solve the accident caused by the winter road freezing.

To this end, the present invention is to install a heating tube on the bottom of the road surface in the interval of frequent frost accidents such as an uphill road, a curve road or a shady road, so that heat dissipation is performed by each section to prevent freezing of the road. Present a new system.

Hereinafter, the configuration and operation of the present invention will be described in detail.

According to the present invention, a heating tube (2) buried under a lane (1) is installed on the basis of a section in which freezing accidents such as an uphill road, a curve road, or a shady road are frequent, and to provide heat to the heating tube (2) for circulation. It is composed of a heat supply device (3) provided for each unit, and a control device (4) to operate by controlling the heat supply device to have a heat dissipation for each section of the lane.

Fig. 1 shows an example of the system configuration according to the present invention in a one-way secondary road, in which the heat pipes 2 connected to the respective heat supply devices 3 are respectively provided with independent heat supply devices 3 on both sides of the road. (1) Pass the lower part of the center and change the direction from the end of the section to the other part of the road, and continuously install it on the underside of the road and apply the freezing prevention system that is operated independently in both lanes separated by the center line (5). It is shown.

Figure 2 shows that in the case of a one-way primary road, one heat supply device is used, and the heat pipe can be configured as a single system connected to the heat supply device by making a U-turn through the driving lane to the opposite driving vehicle. Regardless of the type of road, it is applied by embedding a heating tube having a proper heat supply capacity on each lane regardless.

The heat supplied in the above configuration uses hot water or heat transfer depending on the road environment, and may be used in combination in some cases.

Figure 3a shows a structure using hot water heat, Figure 3b shows a structure using heat transfer, Figure 3c shows an embodiment using a mixture of hot water heat and heat transfer in consideration of the conditions of the road environment and maintenance, etc. It is selectable, and in the case of using electric heat, a method of using cheap midnight power is preferable.

In the case of using hot water heat, a general industrial boiler is used as a heat supply device, and a heat pipe has excellent heat dissipation characteristics and a corrugated pipe (2a) can be used to prevent freezing by expansion and contraction, and to prevent freezing of circulating water. Antifreeze is used, and in the case of using heat transfer, a heat wire is built in the heat transfer pipe (2b) to prevent a short circuit.

In the case of new roads, the laying of heat pipes is to be buried at a depth of about 30cm from the road along with the construction of roads.In the case of existing roads, after cutting the road surface, the hot pipes are buried, and the concrete is first coated with heat-resistant cement. Or use the method of finishing with asphalt or constructing a block with a built-in heating tube and installing it on the cutting part of the road and then binding it using a binder or the like.

4 is a view showing a state of construction on the existing road using a cutting machine (6) to cut the road surface to form a groove (7) after installing the heat pipe (2), the heat-resistant concrete (8) is placed around After covering the heat pipes by the process of coating with asphalt or concrete according to the road form is shown that the heat pipes are buried.

Figure 5a is a block used to cut the road surface after cutting the groove into a block (9) containing a heating tube in the groove and bonded to the road surface with a binder (10) is used as a binder using a resin-based adhesive It is used as a method of promoting curing by mixing an appropriate amount of curing agent during construction.

5B illustrates an embodiment of the above-described block, in which an internal heating tube protrudes from both ends of the block 9, and a connecting portion 11 is formed on the protrusion to connect the connecting portions of both blocks to the joint 12. The construction is made in such a way as to connect each connection to the joint while installing the block on the cut groove and fill the space with binder or concrete.

Fig. 6 shows the control device 4 of the road ice prevention system according to the above configuration, in which the control device includes a manual operation mode 13, an automatic operation mode 14, and a remote control mode 15. It is configured to control the on / off of the heat supply according to the output signal of the.

The automatic operation mode 14 is configured to operate automatically when a predetermined condition is met. The automatic operation mode 14 operates automatically when snow is detected by a sensor 14a installed outside the system. It is controlled by the road management station 15b by using the wired / wireless network 15a connected to the control device. The manual operation mode 13 is operated by the decision of the patrol personnel and the snow falls by the weather observation. It is a control method that is configured together with automatic control or remote control in a way to prevent road ice in advance by operating the system when there is a risk of accumulation or accumulation.

The configuration of the control device can be integrated management of the frost prevention system installed independently for each section to reduce the cost required for maintenance, and can be operated in a variety of control methods according to the conditions to quickly respond to snowfall Will have the effect.

The present invention by the above configuration is to realize the technical idea to prevent the road from freezing by the source of heat supplied from the roadbed under the bed, each configuration described above is described as an embodiment It is not excluded that it is feasible in form.

The present invention by the above configuration can prevent accidents due to freezing by installing in a high section of the risk of accidents caused by winter freezing in advance, it is possible to prevent accidents due to freezing in advance, recurring enormous snow every year with only the initial investment The cost and effort can be reduced, and the socioeconomic loss can be reduced by drastically reducing the icebreaking traffic accident, which constitutes a large part of the traffic accident.
